An Introduction


Sickle Cell Anemia is an inherited blood disorder that arises from gene mutation. As a result, the affected hemoglobin molecules will have a tendency to stick to one another, forming abnormal strands of hemoglobin within the red blood cells. The cells that contain these strands become stiff and elongated which results in their blood cells changing into the rigged shape of a sickle shaped (a farm tool)—hence the name.

Since it affects the blood cells, you can most likely guess that the problem is a blood disorder. The change in cell shape affects the hemoglobin, which helps carry oxygen to various parts of the body.
